please unzip the package you got from themeforest.net ONE time. You should get a folder which contains PSDs, Docs and another zip file (which is called coalition.zip. This zip file is the right file. Go to your wordpress admin panel and navigate to Appearance > Themes. Then select the coalition.zip file, upload & install it. You can also unpack this zip file and upload the resulting folder via ftp to wp-content/themes.

Hey, I’m having the same problem RickZeien is having — can’t upload theme due to missing style.css stylesheet — only with the PROPULSION theme. Is the solution for the Propulsion theme the same as the solution for the Coalition theme?
